Surface Variables Description of Axion Topological Materials
Francisco J. Solis, Hugo GarcÃa-Compeán, Hugo García-Compeán
We study the response of axion topological materials under the presence of external static electric and magnetic fields. We focus on the macroscopic quasi-static magnetoelectric re…

The Feynman-Kac formula in deformation quantization
Jasel Berra-Montiel, Hugo Garcia-Compean, Alberto Molgado
We introduce the Feynman-Kac formula within the deformation quantization program. Constructing on previous work it is shown that, upon a Wick rotation, the ground state energy of a…

Star exponentials from propagators and path integrals
Jasel Berra-Montiel, Hugo Garcia-Compean, Alberto Molgado
In this paper we address the relation between the star exponentials emerging within the Deformation Quantization formalism and Feynman's path integrals associated with propagators…
